Specification of Letters Patent.

Patented May 5, 1908.

Application filed November 17, 1906. Serial No. 343%;04.

T 0 ail :whom it mag concern: Be it known that I, FRANK ECKERT, a resident of Chicago. in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Coin-Detectors, of which the following is a full, clear, and e1:- act-description. The invention relates to devices commonly known as coin-detectors which are adaptedto control the passage of checks or coins to coin-controlled devices for the purpose of eliminating bogus-coins or slugs. The present invention designs to provide a simple and efficient device whereby trulyf formed or genuine coins or checks will be disposed in one direction and 'bogus coin's or checks or defective coins will be diiferen tially disposed. l

A coin or properly; formed check is usually provided with a circumferential bead or rim of a particular size not present inbogus coins or slugs and the invention designs to utilize this characteristic of genuine tokens in the elimination of bogus checks or deficient coins. It has heretofore been common to employ a test alone, however, has been found insufficient in practice to eliminate differently formed checks, slugs or bogus coins of substantially the sameweight as a token for One object-of the invention is to provide an improved detector which willbe operated to displace only a truly formedtoken in one direction while another will be displaced otherwise.

Another object of the present invention'is to provide a gravity operated movable coinsupport which will be operated by the token. to deliver a genuine token or coin having all of the characteristics of such a genuine coin in one direction and which will reject a slug or bogus-coin.

The invention further designs to provide a simple, efficient, gravity-operated coin-detector of improved construction.

The invention consists in the several novel 3 features hereinafter set forth and more 1 .1I-- ticularly defined by claim at the conclusion 3 hereof.

In the drawings: Figure l is a vertical section taken through a device embodying the invention. Fig. 2 is a Fig. 3 is an enlarged-sect onal view showing 'the improved detector and the manner of disposing a coin or truly formed check ofthe lan of the same.

proper size, form and Weight. Fig. 4'is a siinila-r view showing .the manner of disposing of'a slug having a beadededge on one side and a fiat face at'the other, and the-man vice is designed. Fig. 6 is a similar view,

showing the manner of displacing a coin of insuflicient weight into the rejector-channel. The coin detector is usually. associated with some coin or check controlled device or mechanism and in F i 1 of the drawings 1() denotes the front wall of an mclosnig casing of a coin-controlled apparatus and in which is provided, as usual, a coin-receiving'slot 11 through which the tokens can be inserted. and deposited.

An inclined channel, 12, is adapted to receive the tokens and direct them to the coin-detector. A guide or channel 14 is provided to which coins or tokens of the proper size and shape will be directed by the testing device and a guide, or channel-l3 is provided for the rejected tokens. Usually the guide 14 delivers the check or coin to a device. to be controlled or operated thereby and the rejector-charnnel 13 directs the re jected coins or sings to a refunding channel or into the machine to be retained. I

It willbe understood that the improved detector may be associated with any machine or check-controlled device -and that the coins or checks may be disposed of in any desired Way by the improved detector.

' The bottom of channel 12 may be pro- .vided with an opening 15 through which I tokens materiallysmaller in diameter than genuine checks or tokens will fall to eliminatc them before they passto the detector.

Coin guide or channel 12 is inclined so that a coin will gravitate thereon at substantially uniform speed. and an inclined a'bhtlnent or deflector 16 may bc providcd 't-o rctard the coin in transit to the detector in event the deposit'or attein its to force atoken through the channel zit materially higher speed than'that caused by gravity alone. The side-wall of the guide 12 is cutaway as at 17 to allow the token to be delivered thereon by coin-channel guide 12:

The lever is pivotally sustained by a pintle or shaft 19 having its terminals 20 jturnaled v in extended portions of the sidewalls of the coin-guide 12.

side of notch 27.

"travel of. the lever.

the'lov er face-of the token and determines This lever serves as a coinsupport and is-movably sustained so that it will be operated by a token. The movable support is weighted so that it will be held normally. in position to receive tokens and will be shifted by gravity of the token to displace or direct them into either of the guides for the tokens. To restore the gravityoperated coin-lever 18 to, and "to hold it in,

normal position and to prevent the operation of the lever by'a tokenof deficient weight, a counter-weight 21 is suspende by a rod 22 which is pivotally connected as at 23 to the lever at one side of the lever-pivot. By suspending the counter-weight from a pivotal connection on the lever the weight is more evenly applied to counter balance the end of the lever on which the token is temporarily held. The tilting lever or en port extends longitudinally of the channel and centrally thereof and has secured thereto wings or supports 24 which are adapted to prevent the tokens from lateral displacement while the tokens are on or passing over the lever. The lever is held normally in pro er position with respect to coin-channel 12 y engagement of its outer end 25 with the bottomof a stop-bar 26. Near the outer end of the lever is provided a recess or notch 27in which the circumferential bead or rim of a truly formed check or genuine coin can pass. At the outer end of this notch is anabutment or sto 28 whereby a genuine coin or check will be eld' on the lever during the tilting movement impartedthereto by the token itself. The lever is also slightly rejcessed as at 29 to direct the edge-p0 tion of the token over an abutment 30 at the upper Abutments 28 and 30 are so disposed with respect to each other that only a rim of the proper size on a genuine check or token can pass therebetween so that it will be held by abutment 28 during the Abutment 30 engages the vertical position of the edge of the coin with 'respect to abutment 28 so that only a token having a rim or bead which will ass between abutments 28 and 30 will be eld on the lever by abutment 28 and displaced in one direction. 'i. e. that for pro erly formed checks or coins. The front en of the stop bar 26 serves as a stop or abutment which arrests thetokens at the proper point to ,cause them to be held if of't'he pro )er form by the lever and this stop is inc ined or under-cut as at 32'to direct a properly formed coin or token so that it will be held by abut.

ment 28. A coin of the proper size and form will bestopped so that a portion thereof will remain on a rest 33 formed on the lever and thereby a genuine token will be held in such relation withrespect to the lever that the outer edge or rim will engage abutment 28. Rest 33 terminates at a point slightly within the periphery of a genuine token engaging abutment 28 so that a token of lesser diameter will be differently disposed on the lever and with respect to abutment 28. By terminating rest 23 as aforesaid, a genuine coin of smaller diameter can pass, into a depressed portion or-recess 34 which causes the token to be held at. such an angle with respect to the lever that even if the usual beaded rim is present the coin or to en will be so directed by the rest and abutment that it will ride over abutment 28. The weighted end of the lever is provided with an extension or guard 35 which is adapted to block the coin-channel or guide when the lever is out of normal position to detain a'succee ding token if one is deposited before the previo sly deposited token has been discharged troin the letter.

The o oration and manner of disposing of a truly ormed check or coin is illustrated in Fig. 3. A deposited coin directed by coin.- guide 1 2to the gravity-operated coin-support passes over, the inner end of the lever and into. position indicated by the dotted lines, i. 6., at the'outer end of the lever, the

bead or rim of the coin passing between abutments 30 and 28, beingdirected thereinto by inclined abutment 30 of the lever and stop 32. lies on rest 33 so that the relation of the token with respect to the lever will be such that the rim will be held against slipping off the lever by abutment 28. This occurs only when the token is of sufficient diameter tobe held on rest 33 and when the circumferential bead is of such size that it can pass between abutments 28 and 30. In its descent the token encounters undercut stop 32 which prevents the coin from rebounding upwardly and aids gravity in directing the rim of the coin against abutment 28. Such a token is of sufficient weight to o erate the inner end'of the lever downward y and overcome the weight of the other end of the lever, so that as soon as the coin is arrested and engages abutment 28 of-the lever, the lever will swing about its pintle into position indicated by dotted lines, abutment 28 reventing the token from sliding 03 the ever. Thus a genuine coin or token will remain on the lever The opposite rim-portion of this token.

the coin strikes an abutment 36 as the lever 'is swung and thereupon the token will be released from abutment 28 and discharged into guide l i which is designed to conduct genuine coins and properly formed checks to the coin-operatedor controlled mechanism.

In Fig. 4 is illustrated the o eration of the detector when a slug or c-hec of the same diameter as a genuine coin but of improper f0rm,is deposited. The slug there shown is provided with one smooth face and a bead somewhat wider than the circumferential bead'on a coin, on the other face. When such a tokeii is-deposited with its smooth face 11' permost the. head on theunder face will ri e o vera'butments 30 and 28, so that as soon asthe'lever is titled by the token it will slide downwardly on the lever and fall mto the rejector-channel 13, thus being differently disposed from a genuine coin or.

token. If such a slug is deposited with its beaded face u)permost, it will be likewise disposed of and the lever will operate in the same manner to direct it into, the rejectorchannel.

- In Fig. 5 is shown the operation of the detector when a genuiue coin .of smaller size than that for which the machine is designed,

is deposited. Suclnav coin will be momen tarily arrestdby stolpbar 26 and the circumferentialbead-wi ride over abutment- 3.0 but the upper portion of the coin will rest on the'de ressed portion '34 of the lever, thus causing t e coin'to be disposed at an angle with respect to the lever. Resultantly the coin will be disposed so that its lower edge or rim will be directed over and not engage abutment 28, and'wher the lever is depressed by the token it willrheover abutmen-ts 30 and 28' and be discha rget'l into the rejectorchannel. a

In Fig. 6 is illustrated the operation of the device when a token is deposited which is of sufiicient weight to tilt the lever slightly to move the lever and the token away from stop 32 but of proper form and size to be held by the lever. Such a token may partially tilt the lever, and be held suspended on the lever as shown in the drawing. By jarring the machine which is usually done by the deposit'or when the machine is not operated in re sponse to a deposited token, the vibration will be sutlicient to release the token from abutment 28 so that it will ride over said abutment and be deposited in the rejectorchannel. It, perchance, the machine is left in position shown lIl'Fig.'6, without removal of the token from the lever. and :a genuine token isthereafter deposited, the latter will be arrested by guard 35 until the slug has been released. As soon as the slug is discharged from the lever the device will be restored to its normal position, whereupon support serves also as a shifter for tokens having a circumferentialbead of proper size and that abutment 28 engages the periphery of a truly formed token only, while abutment 30 engages a face of thetoken immediately inside of the bead, and. that only a token of proper shape and size will be'shifted by the lever in one direction and. differently disposed from improperly formed tokens.-

Manifestly the invention provides a simple coin detecting device which disposes of genuine coins or checks in one direction and re-' u s I s v ects or diiierently disposes of tokens def1 cient in size or having a rim of improper form.
